Bergamot oil is made from a tree that can grow up to four meters high, with star-shaped flowers and smooth leaves, bearing citrus fruit resembling a cross between an orange and a grapefruit, but in a pear-shape. The fruit ripens from green to yellow.
The oil is one of the most widely used in the perfumery and toiletry industry and forms, together with neroli and lavender, the main ingredient for the classical 4711 Eau-de-cologne fragrance. It is used to flavor Earl Grey tea.
The name is derived from the city Bergamo in Lombardy, Italy, where the oil was first sold.
Bergamot oil can be used in the treatment of depression, stress, tension, fear, hysteria, infection (all types including skin), anorexia, psoriasis, eczema and general convalescence.
